Answer:
This would be a reflection over the x-axis and a vertical stretch by a factor of 3.
Step-by-step explanation:
We can identify the shift over the x-axis by looking at the negative in the front.
We can identify the vertical stretch by noting that the variable is being multiplied by 3, which makes the y value go up 3 times as fast.
Answer:
b
Step-by-step explanation:
Answer:
Part 1) The measure of angle d is 65°
Part 2) The measure of angle c is 89°
Part 3) The measure of arc a is 131°
Part 4) The measure of arc b is 47°
Step-by-step explanation:
we know that
In an inscribed quadrilateral, opposite angles are supplementary
step 1
Find the measure of angle d
∠d+115°=180°
∠d=180°-115°=65°
step 2
Find the measure of angle c
∠c+91°=180°
∠c=180°-91°=89°
step 3
Find the measure of arc a
we know that
The inscribed angle measures half that of the arc comprising
115°=(1/2)[99°+arc a]
230°=[99°+arc a]
arc a=230°-99°=131°
step 4
Find the measure of arc b
we know that
The inscribed angle measures half that of the arc comprising
∠c=(1/2)[arc a+arc b]
substitute the values
89°=(1/2)[131°+arc b]
178°=[131°+arc b]
arc b=178°-131°=47°
Table 1 because what you multiply to go from x to y is different for each set of points
1/6 + 2/3=
1/6+4/6 being 6 the common denominator
5/6 which is in simplest form
